## 5. Engineering Risks & FAQ
- **Caution**: 
- **Caution**: 
- **Caution**: 

### Q: What materials are used in boom sections for different applications?
**A**: Boom sections are typically made from high-strength steel grades like Q345B, Q550D, or WELDOX for heavy-duty applications, while aluminum alloy is used for lighter applications where weight reduction is critical.

### Q: What components are included in a typical boom section BOM?
**A**: A standard boom section bill of materials includes lifting lugs or attachment points for connection, seals or wipers to prevent contamination, and wear pads or slide blocks to reduce friction during telescopic movement.

### Q: How do boom sections create telescopic boom structures?
**A**: Individual extendable segments nest inside one another and slide using wear pads, allowing the boom to extend and retract while maintaining structural integrity through high-strength materials and precise engineering.

## 6. Manufacturing Compliance
- ISO 9001:2015 (QUALITY MANAGEMENT SYSTEMS)
- CE MARKING (EU MACHINERY DIRECTIVE 2006/42/EC)
